I'm wondering if there is any info regarding expansion and penetration comparisons of Round Nose vs Spitzer bullets, assuming equal weight. :confused:

For instance Hornady makes a .338 cal 250gr RN and a 250gr PSP (pointed soft point).

I know that the spitzer should have superior ballistic coefficient.

I was looking at these 2 bullets (www.MidWayUSA.com) and the spitzer actually has higher sectional density.

Which will penetrate deeper? Will expansion be the same or will one of these shapes reliably expand to a greater frontal area? :confused:

Midway has reversed the BC and SD numbers for the round nose. It should read SD=.313 and BC=.291
 
As far as performance, I found the 250gr Hornady RN's hold up very well even hitting bone and even though they don't shoot as flat as a spitzer they sure shot a tighter group in my 338. If your shots are inside 250 yards then why not give them a try.
Sometimes they may not feed quite as nicely if they are seated longer for proper land clearance.
 
If the bullets are built exactly the same (same lead as well as same jacket material, thickness and profile) and pushed to the same velocity, the round nose will open faster/easyer increasing wound diameter but limiting penetration.
 
I guess that I should have added that the advantage of the round nose is that due to the fact it opens up easyer (epecaly if there is a lot of exposed lead at the tip) the jacket can be made thicker and still have the bullet open up at low velocity.

Back in the day before super bullets this gave greater penetration over the standard spire points wich had thiner jackets needed for reliable expansion as velocity dropped off at longer ranges. And of course the longer ranges were the whole idea behind spire points.
 
Boer Seun, feast your Vulcan squinties on this!

Boer seun wants!!!!
Boer won't sleep for weeks
Boer needs to know where Noel lives
Boer needs to know if he has a Rotweiler
Boer Needs to know If there is an alarm system in Noels house
Must save te RN shells....must save the....must save...
Boer needs to go was the break-marks out of his under-wear.

That's enough from the peanut gallery.:p
C'mon Tod, out of all the game you have shot, how many have been beyond
250 yards.

I'll be the first to admit the spitzers are generally the way to go if you hunt in mixed cover but these big fatties shouldn't be overlooked for in the timber.;)
Besides, who needs to be cool when you're classic.:)

Boer Seun, I must say you are a bit excitable!:D
 
Aha! So I guess we all more or less in the same boat. :redface:
I believe I am close to the same count as you, bad memory,:rolleyes: and in all that time I think I may have nailed four animals at or beyond 250, with spitzers, round nose and whatever else. I haven't checked my manuals but I'd bet they fly darn close (in trajectory) to that range, although losing a bit more steam they will still hit with enough wallop to keep some of us "classic's" fans satisfied.

FWIW Tod, I am going to try some Interbonds this fall, just in case I see a ram a ways off while looking for bullwinkle.:redface:
Old Nugget does quite a sales pitch and peaked my interest, for now...;)
 
although I probably face no real disadvantage in the field using a round nosed bullet, you wont see me loading one anytime soon :)
​
 
I've always used bullets based on the possibility of that long shot appearing but really I have shot very few animals at any distance. My 3 longest shots are 220, 280 and 320 yards, everything else pretty much inside 150 yards.
